A winch relay

Abstract

Disclosed in the invention is a winch relay comprising a housing, output terminals, power positive terminals, a power negative terminal, contact bridges, and a push assembly. The output terminals, the power positive terminals, the power negative terminal, the contact bridges, and the push assembly are assembled inside the housing. The output terminals contain a first output terminal and a second output terminal; and the power positive terminals contain a first power positive terminal and a second power positive terminal. The contact bridge include a first contact bridge enabling the first output terminal and the first power positive terminal to be connected under the effect of the push assembly and a second contact bridge enabling the second output terminal and the second power positive terminal to be connected under the effect of the push assembly. The first power positive terminal or the second power positive terminal is connected with a protective switch. With the winch relay, reverse rotation of the winch still can be controlled after automatic power failure of the protective switch and thus the rope can be loosened after the automatic power failure of the protective switch, thereby improving safety.

Description

technical field [0001] The invention relates to the field of outdoor emergency equipment, in particular to a winch relay. Background technique [0002] In the prior art, the winch relay is a device mainly used to control the forward rotation and reverse rotation of the winch. During the actual use of the winch, when the winch encounters an overload situation, the protection switch on the winch will automatically cut off the power, so that the winch cannot rotate. [0003] The existing winch relay has the following technical problem: when the winch protection switch automatically cuts off the power, the winch cannot rotate, and the cables on it are usually in a tensioned state. There is also a certain safety hazard if the cable is too tight. [0004] The existing winch relays still have the following technical problems: 1. The existing relays on the market usually need to be equipped with an assembly box, which is made of plastic or iron, and it needs to be equipped with a ...

Problems solved by technology

During the actual use of the winch, when the winch is overloaded, the protection switch on the winch will automatically cut off the power, so that the winch cannot rotate

[0003] The existing winch relay has the following technical problems: when the winch protection switch automatically cuts off the power, the winch cannot rotate, and the cables on it are usually in a tensioned state.

There is also a certain safety hazard if the cable is too tight

[0004] The existing winch relays still have the following technical problems: 1. The existing relays on the market usually need to be equipped with an assembly box, which is made of plastic or iron, and it needs to be equipped with a bottom plate and a card tap line before it can be installed. Only on the winch can the function of the relay be exerted, which has the problem of unsightly exterior

2. All the relays currently on the market are very large in size and occupy a lot of space. Many vehicles and bumpers cannot be installed on them. The application scenarios are limited and the cost remains high.
